Fellow AustrianJoseph Salerno has notably praised Sennholz as an under-appreciated member of the Austrian school who "writes so clearly on such a broad range of topics that he is in danger of suffering the same fate as Say and Bastiat. As Joseph Schumpeter pointed out, these two brilliant nineteenth-century French economists, who were also masters of economic rhetoric, wrote with such clarity and style that their work was misjudged by their British inferiors as 'shallow' and 'superficial'."

2008 U.S. presidential candidate Ron Paulcredits his fascination with economics to meeting Sennholz and getting to know him well. Peter Boettke first learned economics from Sennholz as a student at Grove City College.
